  • Active tectonic stress field analysis in NW Iran-SE Turkey using
           earthquake focal mechanism data

    • Authors: Ahad Nouri MOKHOORİ; Behnam RAHİMİ, Mohsen MOAYYED
      Abstract: NW Iran-SE Turkey is a tectonically active zone related to the Arabia-Eurasia convergence, but the active stress state in this zone has not yet been clearly studied. To improve the knowledge of present-day stress state in this region, optimum reduced stress tensor was analysed. For this, a large number of earthquake focal mechanisms (277) were collected. The analyses show most mechanisms exhibit strike-slip to thrust faulting. These data indicate that this region is dominated by an N158 degrees maximum horizontal compressive stress (S-Hmax) belonging to a transpressional tectonic regime. In the scale of the study area, the relative magnitude of the intermediate and minimum principal stress axes do not differ much (phi = 0.09). Brittle deformation in this area is dominantly accommodated by a combination of strike-slip and thrust faulting (A phi = 1.82 to 2.30). The analyses reveal that two sets of faults show a high tendency to slip and reactivate. These sets contain NW-SE-striking right-lateral and NNE-SSW-striking left-lateral faults. The results of this study may help to study the active seismicity, tectonic activity, and seismic risk in this region.

  • Time frame for future large earthquakes near Istanbul based on
           east-to-west decelerating failure of the North Anatolian Fault

    • Authors: Fatih BULUT; Asli DOGRU
      Abstract: Large earthquakes that have occurred along the North Anatolian Fault (NAF) were analysed to elaborate the time frame of future large earthquakes near Istanbul. The historical earthquake catalog that was compiled covered 1 nearly complete and 2 fully complete failures of the NAF between 1250 and 2000 AD. These data were used to investigate the space-time systematics of M>= 7.0 earthquakes. The catalogue identified an east-to-west decelerating domino-like failure of the NAF. The deceleration starts around the western tip of the 1944 Gerede rupture. This suggested that failure of the remaining unruptured similar to 250-km section in the west (Istanbul to Saros) will take substantially longer than failure of the already ruptured similar to 950-km section in the east (Karliova to Izmit). The calculations indicated that complete failure of the NAF will last for 243 +/- 3 years. The deceleration could not be explained by strain partitioning between the subparallel strands of the NAF in the Marmara region.

  • Time-dependent model for earthquake occurrence and effects of design
           spectra on structural performance: a case study from the North Anatolian
           Fault Zone, Turkey

    • Authors: Ercan ISİK; Yunus Levent EKİNCİ, Nilgun SAYİL, Aydin BUYUKSARAC, Mehmet Cihan AYDİN
      Abstract: We have investigated the time-dependent seismicity model of the earthquake occurrence on a regional basis through the North Anatolian Fault Zone (NAFZ). To that end, the studied region has been subdivided into 7 seismogenic zones considering the seismotectonic criteria, and then regional time and magnitude predictable (RTIMAP) model has been performed. Intervened times and magnitudes of main shocks produced in each zone have predictive properties defined by the RTIMAP. The probabilities of the next main shocks in 5 decades and the magnitudes of the next events have been estimated using the formation time and magnitude of the past events in the zones. In the second step of the study, we have considered 17 settlements located on the NAFZ to perform point-based site-specific seismic hazard analyses and to determine the design spectra and earthquake parameters using updated Turkish Earthquake Hazard Map. Eigen value and static adaptive pushover analyses have been applied for the sample reinforced concrete building using the design spectra obtained from each settlement. This sample building has been modelled with the same structural characteristics (i.e. material strength, column and beams, applied loads, etc.) for all of the settlements. We have determined that the earthquake building parameters differ from each other which indicates the significance of site-specific seismicity characteristics on the building performance.

  • Peritectic assemblage entrainment and mafic-felsic magma interaction in
           the Late Oligocene-Early Miocene Karadag Pluton in the Biga Peninsula,
           northwest Turkey: petrogenesis and geodynamic implications

    • Authors: Namik AYSAL; Abdullah Sinan ONGEN, Sabah YİLMAZ SAHİN, Cem KASAPCİ, Nurullah HANİLCİ, Irena PEYTCHEVA
      Abstract: The Hellenic subduction system governs the entire Aegean region through the creation of a migrating magmatic arc that has existed since the beginning of the Early Cenozoic. The Karadag Pluton is situated in the NW part of Turkey and represents one of the distinct snapshots of this subduction system during the Late Oligocene-Early Miocene Period.iod. It consists of 2 major lithological units, based on their petrographic and geochemical features, comprising: 1) main plutonic facies (SiO2 < 70 wt.%) that are dominated by hornblende- and biotite-bearing monzogranite, quartz monzonite, and granodiorite, and 2) late-stage more felsic facies (SiO2> 70 wt.%) that are represented by cordierite-free and cordierite-bearing leucogranites. Zircon U-Pb laser ablation inductively-coupled plasma mass spectrometry and K-Ar dating revealed crystallization and cooling ages of 23.9 +/- 0.5 Ma and 20.2 +/- 0.9 Ma for the main plutonic bodies, and 22.0 +/- 1.1 Ma for the leucogranite facies, respectively. The pluton had a high-K calc-alkaline affinity and exhibited a metaluminous to peraluminous (aluminum saturation index of

  • Multiple fluid-mineral equilibria approach to constrain the evolution of
           thermal waters in the Hisaralan geothermal field, Simav Graben, western
           Turkey

    • Authors: Ali GOKGOZ; Halim MUTLU, Mehmet OZKUL, Ali Kamil YUKSEL
      Abstract: In this study seasonal changes in the geochemical and stable isotope compositions of Hisaralan thermal waters in Simav Graben, western Turkey, were investigated with regards to a variety of mineral-water interactions and mixing processes. The Hisaralan and Emendere geothermal waters, with temperatures of up to 99 degrees C, were mostly of Na-HCO3 and Ca-HCO3 types. The delta O-18 and delta H-2 values of the Hisaralan waters ranged from -9.32 parts per thousand to -8.73 parts per thousand and -65.02 parts per thousand to -61.10 parts per thousand, with maximum seasonal differences of 0.3 parts per thousand and 1.8 parts per thousand. The Emendere waters were represented by a more positive range of delta H-2 values (-54.95 parts per thousand to -54.61 parts per thousand), while their delta O-18 compositions (-9.04 to -8.41 parts per thousand) were very similar to those of the Hisaralan waters. The stable isotope compositions of the Hisaralan thermal waters were consistent with those of the global meteoric water line, whereas the Emendere waters closely resembled those of the Marmara meteoric water line. The delta C-13 of the dissolved inorganic carbon varied from -4.33 parts per thousand to -2.77 parts per thousand for the thermal waters and from -13.84 parts per thousand to -12.51 parts per thousand for the cold waters. These values indicated a marine carbonate origin for the former and an organic source for the latter. Sulfur isotope systematics of dissolved sulfate in the Hisaralan geothermal waters indicated that the sulfate was most likely derived from the dissolution of marine carbonates and terrestrial evaporites. Chemical geothermometers applied to the Hisaralan thermal waters yielded average reservoir temperatures of 123 to 152 degrees C, which were rather consistent with those estimated using the silica-enthalpy (146 to 154 degrees C) and chloride-enthalpy (142 to 178 degrees C) mixing models. The recharge elevations of the thermal waters that were computed from the delta H-2 compositions were between 1060 and 1330 m.

  • Present day strike-slip deformation within the southern part of the
           Izmir-Balikesir Transfer Zone based on GNSS data and implications for
           seismic hazard assessment in western Anatolia

    • Authors: Eda Esma EYUBAGİL; Halil Ibrahim SOLAK, Umre Selin KAYAK, Ibrahim TİRYAKİOGLU, Hasan SOZBİLİR, Bahadir AKTUG, Caglar OZKAYMAK
      Abstract: Herein, a combined analysis of Global Navigation Satellite System-derived strain rate maps, in accordance with recent seismicity, was presented to reveal that the N-S extension is accommodated primarily by strike-slip faulting of the Izmir-Balikesir Transfer Zone (IBTZ), where a counter clockwise rotation (similar to 25-100 degrees/Myr) along the vertical axis is dominant. The results indicated that strike-slip segments within the IBTZ show variable transport sense and amount of slip along them, and they connect by hard linkage relay ramps with the dip to oblique slip normal faults. According to the strain map, the Karaburun Peninsula has the largest strain rates, at 137 nano strain (nstrain)/yr extension (NE-SW) and 126 nstrain/yr (NW-SE) compression. To the south, the largest strain areas begin to shrink where the NW-trending sinistral Riedel Fault is located. The smallest strains in the region were measured on the NE-trending Tuzla Fault, compatible with the right lateral component. Based on this, the northern part of the Karaburun Peninsula has the shortest recurrence period in the region. The geodetic earthquake recurrence periods throughout the region comprise 800 yr for magnitudes 7 and above and 70 year for magnitudes between 6 and 7. The period was calculated as 30 years for M> 5.5 (with 99% probability) and 100 years for M> 6 (with 95% probability). These were consistent with the geodetic earthquake recurrence periods (25-30 years for M> 5.5 and 80-100 years for M> 6). This result showed that the seismic hazard sources in the region have increased the earthquake risk, which may cause loss of life and property in the near future.

  • Stacked debris flows offshore Sakarya Canyon, western Black Sea:
           morphology, seismic characterization and formation processes

    • Authors: Derman DONDURUR; Aslihan NASİF
      Abstract: Analysis of ca. 1400 km of multichannel seismic data indicate that the distal part of the Sakarya Canyon within the continental rise is an unstable region with sediment erosion. Fourteen buried debris flows (DB1-DB14), in the stacked form within Plio-Quaternary sediments between 1400 and 1950 m water depth, were observed in the surveyed area. Their run-out distances range from 3.8 to 24.4 km. The largest debris flow DB10 affects ca. 225 km(2) surficial area transporting ca. 15 km(3) of sediment in S to N direction. The debris flows in the area are considered as gravity flows of unconsolidated sediments mobilized due to the excess pore pressures occurred in the unconsolidated shallow sediments arising from the high sedimentation rate. We also suggest that extensive seismic activity of North Anatolian Fault (NAF) located ca. 140 km south of the of the study area along with the possible local fault activity is also a significant triggering factor for the flows. The stacked form of the debrites indicates that the excess pore pressure conditions are formed periodically over the time in the continental rise, which makes the region a potentially unstable area for the installation of offshore engineering structures.

  • Earthquake history of the Yatagan Fault (Mugla, SW Turkey): implications
           for regional seismic hazard assessment and paleoseismology in extensional
           provinces

    • Authors: Mehran BASMENJİ; Husnu Serdar AKYUZ, Erdem KİRKAN, Murat Ersen AKSOY, Gulsen UCARKUS, Nurettin YAKUPOGLU
      Abstract: The southern part of the Western Anatolia Extensional Province is governed by E-W-trending horst-graben systems and NW-SE-oriented active faults. The NW-striking Yatagan Fault is characterised by an almost pure normal sense of motion with a minor dextral strike slip component. Although the settlements within the area have been affected by several earthquake events since ancient times (similar to 2000 BCE), the earthquake potential and history of the Yatagan Fault has remained unknown until a few years ago. Considering the growing dense population within the area, paleoseismology studies were conducted in order to illuminate the historical earthquake activity on the Yatagan Fault. Two trenches were excavated on the fault. Structural and stratigraphic evidence from the both trenches indicated an event horizon of a paleo-earthquake that was dated between 366 and 160 BCE and 342 +/- 131 CE. This event horizon most probably reflected the evidence of the latest large earthquake rupture on the Yatagan Fault.

           larger benthic foraminifera from the Middle-Upper Eocene of the Middle
           East (SE Turkey, Iraq, SW Iran, Oman): New evidence for Arabian Plate
           faunal provincialism

    • Authors: Nazire OZGEN-ERDEM; Felix SCHLAGİNTWEİT, Derya SİNANOGLU
      Abstract: Rogerella aydimi Gallardo-Garcia and Serra-Kiel was described from the Priabonian Haluf Member of the Aydim Formation, Oman. Based on new finds from the Bartonian Hoya Formation of SE Turkey and the Jahrum Formation of Iran, its taxonomic status is discussed herein. It is concluded that it represents a species of Dictyoconus with a simple subepidermal network (1 rafter, 1 intercalary beam) below a thin epiderm. The stratigraphic range of D. aydimi known thus far is Bartonian-Priabonian or Shallow Benthic Zone 1720. The distribution of D. aydimi gives further evidence for a Middle-Late Eocene faunal provincialism of the Arabian Plate (Somalia, Oman, Iran, Iraq, SE Turkey).
